The question I have is I have 1965 plymouth belvedere with a 440 in it. What would look and perform the best? The crossram with the dual quads or the Six Pack. Realizing the 1965 had no special carb setups or did they have dual quad setup. Just I always found dual quads to not be worth the money . But the crossram is cool looking .When did the crossram carb setup be discontinued by Mopar ?
